(4 points) A given relation R={A, B, C, D, E} is decomposed into two relations: R1={A, B, C, E}, R2={B, C, D} a. Based on the given set of FDs F={BàE, CEàA}, is the above decomposition a lossless-join decomposition? Why? b. Based on the given set of FDs F={EàD, BCàA }, is the above decomposition a lossless-join decomposition? Why?

A) if $50000 is invested in a bank account that pays 9.3% of interest compounded on a six-monthly basis, how much money will be in the account after 3 and 12 years? b) if matusalen's father had put $2.0 in the bank when he was born and there, how long would matusalen have had to his death (969 years later) if the interest was 7% per year composed each month and weekly?

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit
